Description

Dual pathways super charge pipe

Technical field

The present invention relates to a kind of air inlet pipe, belong to engine charge component technology field, refer in particular to a kind of suitable The dual pathways super charge pipe using duct plenum for motorcycle engine.

Background technology

In order to increase the intake efficiency of electromotor, commonly used machinery or turbocharging technology on automobile, should There are the following problems in the application for technology:

1, plenum systems bulky, produces with maintenance cost costly, and service life is relatively short, And gas temperature is high after supercharging, also need with the cooling pressure limiting such as charge air cooler, bypass valve.Because of distribution engine institute Limit, this supercharging mode exposes layout difficulty on electromotor at motorcycle etc., it is difficult to realize.

2, exhaust gas turbine and automobile mechanical turbine all directly link with engine speed, and the rotating speed of motorcycle Scope (1500r/min~10000r/min), speed spans causes greatly control difficulty.

3, motorcycle is low at middle and slow speed of revolution stage moment of torsion, and middle high rotating speed stage moment of torsion is big, and starts at motorcycle In machine actual moving process, middle high rotating speed stage charge can meet use demand, middle and slow speed of revolution stage The weakness that charge is not enough needs improvement badly.

Summary of the invention

It is an object of the invention to overcome shortcoming of the prior art with not enough, it is provided that a kind of dual pathways supercharging is entered Trachea, this super charge pipe can be effectively improved the intake efficiency in electromotor middle and slow speed of revolution stage, ensure simultaneously The charge in high rotating speed stage in electromotor.

To achieve these goals, the present invention realizes according to techniques below scheme:

A kind of dual pathways super charge pipe, includes body, and described tubular body includes the air inlet section of front end With the air outlet section of rear end, described tubular body forms, in air inlet section, the first air inlet pipeline and second that interval is in parallel Air inlet pipeline, the first air inlet pipeline and the second air inlet pipeline conflux into a pipeline in the air outlet section of tubular body, And first air inlet pipeline be provided with check valve, the second air inlet pipeline is provided with ducted fan.

Further, described check valve closes first when tubular body air outlet section air pressure is more than air inlet section air pressure Air inlet pipeline, turns on the first air inlet pipeline when tubular body air outlet section air pressure is less than or equal to air inlet section air pressure.

Further, described ducted fan is driven by motor.

Further, the air inlet section of described body is connected with air filter, and air outlet section is connected with carburetor or fuel injector.

Compared with prior art, it has the beneficial effect that the present invention

The present invention can be good at solving that low cruise stage air-intake negative-pressure is low, charge is not enough in electromotor Phenomenon, improve electromotor intake efficiency, low speed torque and power in increase;Ensure in electromotor simultaneously High-speed cruising stage intake resistance reduces, and improves intake velocity, it is ensured that enough charge, thus effectively Ensure the output of electromotor.

In order to enable the apparent understanding present invention, illustrate to illustrate being embodied as of the present invention below with reference to accompanying drawing Mode.

Accompanying drawing explanation

Fig. 1 is the attachment structure schematic diagram of the present invention.

Detailed description of the invention

As it is shown in figure 1, the new type pressurized air inlet pipe of the dual pathways of the present invention, include body 1, described body 1 inside includes the air inlet section 11 of front end and the air outlet section 12 of rear end, air inlet section 11 and the air filter 2 of body Connecting, air outlet section 12 is connected with carburetor or fuel injector 3, then is connected with electromotor 4.

Above-mentioned tubular body 1 is internal forms the first air inlet pipeline 5 and the second air inlet pipeline that interval is in parallel in air inlet section 6, the first air inlet pipeline 5 confluxes into a pipeline with the second air inlet pipeline 6 in the air outlet section 12 of tubular body, And first air inlet pipeline 5 be provided with check valve 51, the second air inlet pipeline 6 is provided with ducted fan 61.Enter one Step, described check valve 51 closes the first air inlet pipe when tubular body air outlet section air pressure is more than air inlet section air pressure Road 5, turns on the first air inlet pipeline 5 when tubular body air outlet section air pressure is less than or equal to air inlet section air pressure;Institute State ducted fan 61 to be driven by motor.

The operation principle of the present invention is as described below:

1, the middle and slow speed of revolution stage: the air pressure of tubular body air outlet section is more than the air pressure of air inlet section, now check valve Closing, the first air inlet pipeline is closed obstructed, and motor drives ducted fan to produce pressurized air stream, whole air inlet system The air inflow of system is provided by the second air inlet pipeline, forms duct compressed air induction system, increases actual air inflow;

2, the middle high rotating speed stage: along with engine charge demand rise, ducted fan produce air inflow by Gradually less than the air inlet demand of electromotor, the air pressure of air outlet section is gradually reduced, when the air pressure dropping to air outlet section During less than or equal to the air pressure of air inlet section, check valve is opened, and the first air inlet pipeline conducting, meanwhile, motor drives Dynamic ducted fan continues to produce air-flow, thus the air inflow of whole gas handling system is by the first air inlet pipeline and second Air inlet pipeline provides jointly, forms dual pathways compressed air induction system, it is ensured that enough charge.

The invention is not limited in above-mentioned embodiment, if to the various changes of the present invention or modification without departing from The spirit and scope of the present invention, if these changes and modification belong to claim and the equivalent technologies of the present invention Within the scope of, then the present invention is also intended to comprise these change and modification.
